How to Load and Launch

Managing your Bathyscaphe requires a mix of strategy and resource management. You have two primary ways to fill the cargo holds:

• Manual Loading: Use the goods and items you have produced or collected on your islands.
• Superbucks: If you’re short on time or missing a specific item, you can use Superbucks to instantly fill the slots.

You don’t have to wait until every single slot is filled to send the Bathyscaphe on its journey. However, if you try to launch an incomplete vessel, the game will trigger a confirmation prompt asking if you are sure.

Keep in mind: The rewards are directly tied to how much cargo you send. The less you load, the fewer rewards you’ll receive upon its return. It’s usually best to fill it as much as possible to maximize your efficiency!
